# Here's how the cross-compile logic breaks down ...
# CTARGET - machine that will target the binaries
# CHOST - machine that will host the binaries
# CBUILD - machine that will build the binaries
# If CTARGET != CHOST, it means you want a libc for cross-compiling.
# If CHOST != CBUILD, it means you want to cross-compile the libc.
# CBUILD = CHOST = CTARGET - native build/install
# CBUILD != (CHOST = CTARGET) - cross-compile a native build
# (CBUILD = CHOST) != CTARGET - libc for cross-compiler
# CBUILD != CHOST != CTARGET - cross-compile a libc for a cross-compiler
# For install paths:
# CHOST = CTARGET - install into /
# CHOST != CTARGET - install into /usr/CTARGET/

### SRC_URI ###
# This function handles the basics of setting the SRC_URI for a glibc ebuild.
# To use, set SRC_URI with:
#
# SRC_URI="$(get_glibc_src_uri)"
#
# Other than the variables normally set by portage, this function's behavior
# can be altered by setting the following:
#
# GENTOO_TOOLCHAIN_BASE_URI
# This sets the base URI for all gentoo-specific patch files. Note
# that this variable is only important for a brief period of time,
# before your source files get picked up by mirrors. However, it is
# still highly suggested that you keep files in this location
# available.
#
# BRANCH_UPDATE
# If set, this variable signals that we should be using the main
# release tarball (determined by ebuild version) and applying a
# CVS branch update patch against it. The location of this branch
# update patch is assumed to be in ${GENTOO_TOOLCHAIN_BASE_URI}.
# Just like with SNAPSHOT, this variable is ignored if the ebuild
# has a _pre suffix.
#
# PATCH_VER
# PATCH_GLIBC_VER
# This should be set to the version of the gentoo patch tarball.
# The resulting filename of this tarball will be:
# glibc-${PATCH_GLIBC_VER:-${GLIBC_RELEASE_VER}}-patches-${PATCH_VER}.tar.bz2
#
# GLIBC_MANPAGE_VERSION
# GLIBC_INFOPAGE_VERSION
# The version of glibc for which we will download pages. This will
# default to ${GLIBC_RELEASE_VER}, but we may not want to pre-generate man pages
# for prerelease test ebuilds for example. This allows you to
# continue using pre-generated manpages from the last stable release.
# If set to "none", this will prevent the downloading of manpages,
# which is useful for individual library targets.
